Dynamic DNS

Dynamic DNS (DDNS) keeps a hostname pointed at an IP address that changes. It’s perfect for home servers, game servers, surveillance cameras, and anything behind residential internet.

How it works

Your device periodically tells Stackryze its current public IP
Stackryze updates the matching A / AAAA record
The world keeps resolving your hostname to the live IP

Set up dynamic DNS

Create a DDNS token

Open Settings → API → Create token with the ddns:write scope.

Add the records to your zone

In the zone where you want DDNS, create an A record with the placeholder value 0.0.0.0. Stackryze will treat it as a DDNS target.

Send updates

The DDNS endpoint is simple:

curl https://ddns.stackryze.com/update \
  -d "host=home.example.com" \
  -d "token=$STACKRYZE_DDNS_TOKEN"

Stackryze auto-detects your public IP from the request source if you don’t supply one.

Compatibility

The Stackryze DDNS endpoint speaks the de-facto nic/update protocol, so the same clients that work with dyndns.org, no-ip.com, and afraid.org work with Stackryze:

Client	URL
ddclient	`protocol=dyndns2 server=ddns.stackryze.com`
inadyn	`--provider dyndns2@ddns.stackryze.com`
ddns-go	Custom provider, URL: `https://ddns.stackryze.com/update`

IPv6

Stackryze DDNS supports IPv6 out of the box. Send the ipv6 parameter:

curl https://ddns.stackryze.com/update \
  -d "host=home.example.com" \
  -d "ipv6=2001:db8::1" \
  -d "token=$STACKRYZE_DDNS_TOKEN"
